"I went to my dermatologist after suffering throughout my teenage years with acne. They prescribed me Duac gel. The first few days of using it my skin was fine, apart from a few red, patchy areas of skin. In my second week of using it I was in constant pain. My face was inflamed, swollen, incredibly dry and unbearably sore. I decided to stop using it and allowed my skin to recover from my traumatic ordeal, I had honestly never felt worse about myself. I then decided to give it another go, but this time using it for an hour a day, every other day. Once I felt my skin had acclimatised I did an hour every day. Now I can apply it over night without any redness or dryness. My skin has cleared up so much, but i recommend acclimatising your skin."
